If this place is available, book it while you can. The hosts are very friendly and communicative, the location is stellar (the BTS, MRT, and Chatuchak Park are all within a 10 minute walk of the building), and the facilities (pool, gym) are very nice.
I am very sensitive to noise, so I typically sleep with earplugs. I did not need to use earplugs one single night during my stay. It was very quiet. That, combined with blackout curtains, helped me have very restful sleep here.
Book it, and enjoy.
